NON-IRIEFILLABLE BOTTLE.

$PEGII5ICATION forming part of Letters Patent No. 705,481, dated July 22, 1902. Application filed August 22, 1901. Serial N0. 72,876. (No model.)

To aZZ whom it may concern/.

Be it known that-I, JOHN TAMBOER, a citizen of the United States, residing at Paterson, in the county of Passaicand State of NewJersey, have invented certain new and useful Improvements in Non-Refillable Bottles," and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,

reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to non-refillable bot-' designate like parts in theseveral figures,

Figure 1 is a View of a bottle provided with my improvement and having its upper portion shown in sectionto properly illustrate the improvement. Fig. 2 is a vertical sectional view of a certain guard detached from the bottle, and Fig. 3 is a horizontal sectional view taken on the linew w in Fig. 1.

In said drawings, a designates a bottle of substantially ordinary construction except as to its neckportion b. The inside of said neck portion is formed with an integral annular projection c, the bore or channel in this part of the neck being gradually narrowed in diameter or tapered downwardly, as at d. In its upper portion this projection is formed with an annular recess or channel 0, for a reason hereinafter explained,and having reference to the function for which this channel is designed the upper edge of the projection c is rounded or beveledoff, as at f. Below the projection c is formed another annular projection g. Between the two is thus produced in the neck an annular cavity h. This cavity is formed with an annular channel 45, designed to appreciably weaken the neck of the bottle at this point, though not to the extent of rendering the neck fracturable under ordinary 5o handling.

9' denotes one member of the guard. This fitsinto the projection g.

consists of a glass or other non-corrosive cupshaped device, which-being tapered is designed to fit in the annular projection 0. Its top portion is formed-with an annular external flange 7c, which takes against" the top of the projection c to limit the downward moveare secured at diametrically opposite points in the guard, being adapted to -.recede into recessesn in the guard when the latter is introduced into the bottle-neck and when they reach therecess e to spring outwardly into the sameto thus lockthe guard in the bottle. Thus the guard cannot be removed. It is to facilitate the introduction of the catches m of the guard to the recesses that the upper edge of the projection c is rounded or beveled off.

.0 designates an annular valve-seat which The projection and the valve-seat have opposed grooves 10, which receive a retaining-ring q for the valveseat. Against this valve-seat seats an outwardly-opening valve r,'which is pivoted in it, as at .9, serving as an auxiliary guard.

In view of the foregoing it will be seen that after the guard j is in place the bottle will be rendered non refillable by any practical methods. The auxiliary guard, though permitting the outflow of the liquid through the perforations of the guard j, stops the inflow. It cannot be reached by any implement, for the guardj protects it. Moreover, any undue efforts to reach the auxiliary guard by an implement would result in the breaking off of the neck either at. the channel c' or the channel (2, which latter thus subserves a double function.

It will be noticed that the lower end of the guard is spaced fromthe val'ver a distance but slightly greater than the thickness of said valve. Thus the valvecan move only'a distance sufficient'to but just afiord an opening so that the liquid will *flow freely b'utnot so far that said valve'will not promptlyreseat itself at the first inclination of the bottle toward its upright or normal standing position.

the same a distance slightly greater than the thickness of said valve, said guard having openings in its side wall, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of August, 1001.
